Hopefully thats not the case here. Theres not a single spot of rust on the truck anywhere. The windshield is cracked so it will be getting changed out soonsometimes they get rust holes around the windshield and you can really only see them after the windshield is removed
If the plugs are laid out by position, I'd say #8 is the one with the issue. But they all look like there's a bit of oil depositing on them. I'd watch what it does on start up. If it's not blowing blue smoke while under load, I'd suspect it might be a little at idle. Probably valve stem seals. Time to upgrade to the later umbrella style vs the stock o-ring style.looks like your getting some oil into some of the cylinders
Trans ia a turbo 400. I put new plugs cap and rotor in and will do wires this weekend. Its been raining. Ill retorque the tbi while im in there.What's transmission is in this truck. 8 could be oil fouled from trans modulator.
Might be to late this time but gap the plugs at .035".
Inspect the tbi base gasket, retorque the tbi.
At 165k miles, the timing chain is suspect.
Good luck let us know how it goes.
I had that same leak. For me it was the windshield gasket. When it gets old they retract and let water through. Also, if haven’t found one yet I’d get that battery tray. They are getting tough to find. I restored one in a day that was worse than that.
